Abstract

PURPOSE:To suggest indirectly hooking off by performing the bridge cut off to a calling subscriber in an automatic telephone exchange a certain time after the call start time to report that the certain time elapses. CONSTITUTION:On a basis of the number of a called subscriber which a subscriber SUB dials, a marker CM sets a train 1 between the subscriber SUB and an outgoing trunk OGT on a main link ML and transmits storage position information or the like of the subscriber SUB and the outgoing trunk OGT to a call duration monitor device CPE through a path 2. The device CPE extracts the subscriber's number from this information and monitors the outgoing trunk OGT through a path 3; and when the device CPE receives the response indication of the called subscriber, the device CPE writes time information on a corresponding outgoing trunk memory to monitor hooking-off after receiving response time information from a main clock device MTM through a path 4. A certain time after the call start, the device CPE sends the subscriber's number to an offering trunk TKE for talkie transmission through a path 5 and starts the marker CM through a path 6 to perform the bridge cut off through a path 7, thus reporting that the duration of the call is longer.

Description

[Detailed description of the invention] [Field of application of the invention] Unexploded FIF! relates to call monitoring in automatic telephone exchanges.

[Background of the invention]

If a subscriber appears to be talking for a long time in a crossbar exchange or the like, it will be very difficult for a third party to talk to any of the subscribers. Although call waiting services are now available, the proportion of subscribers receiving this service remains low.

Although the third party may be able to find out whether there is a problem or whether a call is in progress by requesting an investigation from the telephone office's maintenance staff, measures to stop the call are generally not taken, so it is not effective to stop the call for a long time. There is no way.

On the other hand, there are many cases where parties who continue to talk for a long time are not even aware of the passage of time.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-described drawbacks of the prior art and to provide a means for prompting long-term callers to end their calls.

[Summary of the invention]

In the present invention, after a predetermined time has elapsed from the start time of the call, an interrupt connection is made to the calling subscriber to notify that the predetermined time has elapsed, and it is also possible to indirectly prompt the subscriber to end the call.

[Embodiments of the invention]

Figure j11 is a relay system diagram showing an embodiment of the present invention.
), ML is the main link, 80B is a calling subscriber, OGT is an outgoing trunk, CM is a marker which is a common control device of the crossbar exchange, and TKE is an interrupt trunk having a talkie sending function.

The MTM is the main clock device, and the CPE determines the time that the SUB is conducting a call using the OGT based on the calling subscriber accommodation location, called party number, and outgoing trunk accommodation location information received from the CM. This is an information processing device that has functions such as monitoring and calculating call frequency.

An embodiment of the present invention will be described below with reference to FIG.

In Figure 1, based on the called party number dialed by the SUB, the CM sets up a train ■ between the SUB and OGT on the ML, and connects the SUB to the CPH through the path ■.
The storage location information of B, the storage location information of OGT, etc. are sent.

CPE adds subscriber data that has been input in advance.

The subscriber number of the 8UB is extracted by referring to the correspondence table between the entry accommodation location and the subscriber telephone number. In addition, the CPE monitors the OGT through the route (■), and when it receives the response indication from the called subscriber, it receives the response time information from the MTM through the (2) route, and then connects the OGT to the SUB via the (3) route. Monitor talk time between called parties.

That is, after writing the 8UB number and response time information on the trunk memory corresponding to the storage position of the OGT, the OG
The CPE monitors the end of the call on T, but since the CPE performs processing that allows it to detect when a certain period of time, for example one hour, has elapsed from the call start time on each trunk memory, the CPE uses route After forwarding the SUB number to TKE, activating an arbitrary CM using route ■, and making a known interrupt connection via route ■, for example, ``Your call has been for exactly one hour. We will notify you of the passage of time every minute, but you may also receive calls from other people while you are on the phone.The call charges will be high, so it is better to keep the calls short. A notification is given and TK'B is restored.

Further, after a certain period of time has elapsed, notification of the elapsed call time is also notified by a short audible signal or the like.

FIG. 2 shows the main circuit portions of the interrupt trunk TKE having the talkie sending function explained in FIG.

In FIG. 2, TKO-N are relays for selecting notification contents to be sent from TKB to 8UB, tko-n are their contacts, and INFO-N are talkie sound sources having notification contents corresponding to the TKO-N relays.

In addition, TH, H, T, and U are the relays that receive and hold the 8UB number from the CPE, and th, h%t, and u are the contacts thereof.
a is a contact point of relay A for link closure confirmation, not shown;
B is the B position relay of this trunk, and b is its contact point.

In addition, IR indicates the register section of this trunk, and it is a function that activates CM from this trunk via a known input register marker connector based on the 8UB number received from %CPE, and allows the CM to transfer information necessary for interrupt connection. has.

In other words, this trunk is activated by the CPE at regular intervals, relay B operates, and the SUB number TH received from the CPE is activated.
, H, T, and U activate CM from the register IR to set an interrupt train from this trunk to the 5tJB, and also activate the talkie sound source corresponding to the notification content selection instruction information TKO-N received from the CPE. By connecting this trunk, the SUB has the function of allowing the SUB to listen to the talkie.

As described above, in this embodiment, the outgoing connection using the outgoing trunk has been described, but the same applies to the connection within the own station.

In addition, in cases where the line is put on hold due to a trunk failure or incorrect charges are made, please refer to the above T.
By combining the KB with a known monitor amplifier, etc., we will provide a means to monitor whether a call is in progress or not, and if it appears that there is a problem, TKE will forward the fault information to 9 CPH and notify the maintenance personnel. It is also possible to improve maintainability by displaying a warning or outputting a message on a typewriter, and to suppress damages such as overcharging.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to automatically make a long-time caller hear a notification regarding the call time after a certain period of time has passed, and it is possible to improve the service provided to third parties, as well as indirectly It is also effective in reducing problems related to fees.

Furthermore, it is possible to improve maintainability in cases where a line is held invalid due to a trunk failure, or where incorrect charges are incurred.
